Science Can Be Revised
科学认知可以修正
Description
Scientific knowledge is provisional — it is the best current explanation based on available evidence, and it can and should be revised when better evidence arrives
Mastery Evidence
- Give an example of a scientific idea that changed when new evidence was found — e.g. people once thought the Sun orbited the Earth
- Explain that scientists update their ideas when experiments give unexpected results, and that this is a strength not a weakness
- Describe why it is important to keep testing ideas rather than just accepting them because an expert said so
Assessment Prompt
Does your child understand that scientific facts can be revised as new discoveries are made — and that this is science working properly, not a sign that scientists were wrong?
